Abstract
Controlled adsorption of organic probe molecules in liquid solutions provides information on the interaction between powder and surface-active additives used in metal injection moulding (MIM). The adsorption of such compounds onto stainless-steel powder and carbonyl iron powder is evaluated by means of XPS. Stearic acid is adsorbed on gas-atomized stainless-steel powder covered mainly by basic manganese oxide. The basic molecule aniline is adsorbed on water-atomized stainless-steel powder having an Si-rich acidic surface oxide. This adsorption takes place preferentially on the silicon oxide. On slightly SiO2-coated carbonyl iron powder, stearic acid as well as aniline are adsorbed. Copyright © 2000 John Wiley & Sons, Ltd.
